I think the designer of this model doesn't understand why these bulbs are usually closed. When it's closed the bulb will create a vacuum and stop water flowing until it can suck in some air when the soil gets dry enough. This is just a fancy funnel and will not do anything to restrict the flow of water through it. The only hope you have of making this slowly water is smashing it into soil so hard that the tip gets mostly clogged.

@JustinLapsley_807014 I had the same thought. I know similar designs with a clay stop at the bottom. This way the soil will pull the water from it slowly. Would it make sense to throw a small clay ball into it?
@JustinLapsley_807014 you're definitely right on how they typically work. I'd argue at the very least though this helps people bottom water their plants, which I believe helps their roots and less prone to root-rot.
I'm curious if potato's idea would work by putting a medium to force osmosis action over pure gravity.
@Zewb_251824 over watering leads to root rot in my experience. roots need oxygen as much as it needs H2O. In large scale gardens you'll typically see ebb and flow systems that flood and drain in order to allow oxygen to fortify root development & health.
@PatrickLamarr_844090 Overwaterring certainly does, my assumption is that this would work better as being used as a glorified funnel to the bottom of the pot/soil. You'd just water it every few days and not every day. But I am by no means an expert.
The idea Potato had that would be interesting would be if you could cork the bottom with a semi-permeable membrane, that would mean that osmosis could come into play and pull the water at a slow/reasonable rate. But there are so many variables that could make it better/worse. 🤷♂
@Zewb_251824 I really think the only option for something like this model is to make a TPU cover to seal the top creating a vaccum. This would allow to siphon the water out as needed once the soil becomes too dry. This is how the bulb style feeders work and is the best solution in my POV.
